//                          High Level Trigger TPC tracker
//       This class encapsulates the Hough transform HLT tracking
//       algorithm. It is used to call the algorithm inside the off-line
//       reconstruction chain. So far the tracker uses AliRunLoader to
//       to get the TPC digits. In the future all the references to
//       runloaders will be removed and the tracker will take as an input
//       the digits tree.
//
